High Performance RF Surge Protector Quarter-wavelength For DIN 7-16 Female To Female

The RF Surge Arrestor offers dependable protection against lightning and surge-induced damage in radio frequency transmission lines. Engineered to maintain signal integrity while safeguarding equipment, it is an essential component for RF networks operating in demanding outdoor and industrial conditions. Featuring broadband performance from DC to 18 GHz (model dependent), this surge arrestor ensures low VSWR (<1.2) and minimal insertion loss, preserving signal quality across various frequencies. The internal surge protection element -typically a gas discharge tube (GDT) - rapidly conducts transient surges to ground, preventing equipment damage without disrupting normal signal flow. Some models feature replaceable GDT cartridges for easy field maintenance.

The body is constructed from high-grade brass or stainless steel with a nickel or silver-plated finish to ensure corrosion resistance and excellent RF shielding. Options for 50 ohm and 75 ohm impedance, DC pass or block, and connector types such as N, SMA, BNC, TNC, and 7/16 DIN make it adaptable to most RF systems.

Applications include antenna feeders, base station transmitters, radar systems, wireless communication links, and microwave test equipment. Designed for long-term reliability, this surge protector meets the rigorous demands of modern RF infrastructure, ensuring stable performance, easy installation, and peace of mind in all weather conditions.

FAQ

Sample Delivery Time

Regular models require 15 days, while some complex connectors require 25 days.

Sample Fee

Most RF connectors are CNC-machined parts and do not require mold-making.

However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.

This fee will be refunded after a 5K bulk order.

Guarantee

Brass RF connectors come with a one-year warranty.

Stainless steel connectors come with a three-year warranty.

The lifespan also depends on the contact material beryllium contacts offer better durability.

ROHS & REACH Compliance

Our products fully comply with ROHS & REACH regulations.

Does LENORF Offer Military-Grade Products?

Yes. We are honored to provide military-grade products with exceptionally stable quality.

Materials

Common materials include:

Body: Brass, stainless steel

Insulator: PTFE, PEEK

Contacts: Brass, phosphor bronze, beryllium copper

Other: Aluminum, titanium alloy

What materials are RF connectors made of?

Body: Brass, stainless steel, or beryllium copper (with nickel, gold, or silver plating). Insulator: PTFE, PE, or advanced low-loss dielectrics. Contacts: Gold-plated brass or beryllium copper for low resistance and durability.

Are RF connectors weatherproof?

Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.

What’s the difference between male and female RF connectors?

Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.

What is VSWR, and why does it matter?

VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.
